Patent number: 11913597Abstract: A product-display system for displaying and securing a retail product. The system may include a retainer having a retainer bracket and a retainer body coupled to the retainer bracket. A retaining cable may be coupled to the retainer body at an opening in the retainer body. A fastener that may be unfastened to release the product from the retainer may only be accessed through the opening of the retainer body such that when the retaining cable is coupled to the opening, no fasteners of the retainer may be visible or accessible. The system may also include a display stem for holding the retainer and product. The display stem may include a recess for receiving at least a portion of the retainer body. The retaining cable may extend through the display stem and may simultaneously transmit power and data to a displayed product. The retainer may be returned to and held on top of the display stem using a retaining cable.Type: GrantFiled: December 1, 2021Date of Patent: February 27, 2024Assignee: Apple Inc.Inventors: Sheng Yang, Eric W.

Patent number: 8685547Abstract: Aspects are directed to recording media with enhanced magnetic properties for improved writability. Examples can be included or related to methods, systems and components that allow for improved writability while reducing defects so as to obtain uniform magnetic properties such as uniformly high anisotropy and narrow switching field distribution. Some examples include a recording medium with an exchange tuning layer inserted between the hard layer and the soft, semi-soft or thin semi-hard layer so as to maximize the writability improvement of the media. Preferably, the exchange tuning layer is granular and reduces or optimizes the vertical coupling between the hard layer and the soft, semi-soft or semi-hard layer of a magnetic recording or storing device.Type: GrantFiled: February 19, 2009Date of Patent: April 1, 2014Assignee: Seagate Technology LLCInventors: Bo Bian, Shoutao Wang, Weilu Xu, Abebe Hailu, Miaogen Lu, Charles C.
